Need some tuning help from some of you Professionals.

I tried pulling -2 degrees all the way up from 5000 rpms on up. That's not alot but if i pull much more it will kill the power on top. On a 3rd gear pull, i really like to see 16 to 17 degrees of timing by the end of the gear. When i get this knock, i might get 13 degrees. I have 5 galls of B33 which is I believe 116 octane. I'll have to run the car more dry because she's got 3/4 tank right now. I'd be best to only have 3-5 gallons of 93 and then mix about 2 galls of B33. I guess the way energy is right now, ya gotta wonder if 93 octane is actually 93 octane at the pump. BP is where i've been getting my gas.

I could also try the slow test that you describe to doing. Rather than driving like at a race, i will ease it from 5k on up and see if easing it vs. beating it makes a difference. These are all certainly good things to try and i appreciate it. It's got me so frustrated because now i want to take it to the track. What's weird is why doesn't it do it in 1st gear at those r's? I guess because the fuel consumption is much greater in the higher gears even at the same rpms. That's my theory.

Thanks.
